SIDE SPRING FOR VEHICLES.

SPECIFICATION forming part of Letters Patent No. 279,507, dated June 12, 1883.

Application filed September 29, 1882. (No model.) I

To all whom it may concern:

Be. it known that I, EMIL TECKTONIUS, of Kenosha, in the county of Kenosha and State of Wisconsin, have invented certain new: and useful Improvements in Side-Bar Springs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanyin g drawings, which form part of this specification.

Myinvention relates to an improvement in side-bar springs; and it consists in a double spring,which is made from a single piece of steel which is bent and curved in opposite directions, and which tapers from its center to ward its two ends, as will be more fully described hereinafter.

The object of my invention is to produce a spring for side-bar buggies which will have a greater length, and therefore a greater amount of elasticity, than the springs now in use, and which is cheaper and simpler in construction than springs which-have heretofore been used for this purpose.

Figure 1 is a side elevation of my invention. Fig. 2 is a plan view of the same. Fig. 3is an inverted view.

In making the spring I take a long bar of steel having the requisite thickness at its center, and which tapers from a suitable distance on each side of the center outward toward each end. These bars can be formed ready to be bent into springs in the rolling-mill, so that all the manufacturer has to do is to give them the proper bend. The top or central portion, A, is to be secured to the under side of the body of the buggy by means of any suitable fastenings that may be preferred.

If clips or clamps of any kind are used, it will save the boring or punching of holes through the spring, and which would have a tendency to weaken it.

At a suitable distance beyond each side of the center the spring is given a bend, B, in opposite directions, so as to throw the ends outward, and thus allow them to be bent backward without coming .in contact with or interfering with each other in their movements.

Just beyond these lateral bends B the curves 0 are formed, which will be greater or less,

according to the amount of play it is desired t0.give the body. Under the center of the spring, as at I), both of the ends are curved upward a suitable distance, so as to allow the spring to pass freely over the reach, and to have any suitable amount of vertical play without touching it. From this upward bend D over the reach the ends are then curved downward and upward, as shown at E, and suitable eyes, F, are formed upon the extreme ends of the springs for attachment to the side bars, either directly or through any inter' vening link or other device that may be preferred. Owing to the shape that is given to this double spring at each end, the expansion and contraction at the endsof the springs will not be perceptible.

Heretofore springs have been made out of two pieces, which have been turned in opposite directions and clamped together at their centers, or of a number of leaves and in a number of different ,ways; but all of these require more or less skilled labor, not only to shape the material, but to apply it to the vehicle after the spring itself is produced. By the construction here shown the springs can be produced ready for use, with the exception of the bends, in the rolling of the bars themselves. V

The great advantage of this spring over all others consists inits great flexibility, being less liable to break than any of the springs now in use, owing to the peculiar shape that is given it, and its cheapness, and the ease with which it can be applied directly to the bottom of the body.

This invention differs from the spring patented by me August 15, 1882, in making the,

spring tapering from each side of the center toward the ends and curving each end upward, so as to pass over the reach, and then upward at the ends, where the eyes are formed, fol-iattachment to the side bars.

Having thus described my invention, I claim- A spring for sidebar buggies, made from a single piece of metal, and which is tapered from near the center toward each end, the In testimony whereofI affix my signature in ends being doubled back upon the spring so presence of two witnesses. as to extend, in opposite directions, and each end curved upward at D, so as to pass over EMIL TEOKTONIUS. 5 the reach, then curved downward at E, and then curved upward and made to terminate in \Vitnesses: an eye, F, for attachment to the side bars, sub- Trros.
